With Office 365 Home Premium, you and your family can stay connected whether at home or on the go. A subscription to Office 365 Home Premium allows you to have all of your trusted Microsoft Office applications – such as Word, Excel, PowerPoint and Outlook – installed on up to five household PCs, Macs, tablets or mobile devices, and you will always have the latest new features and services when capabilities are added during the year.

With Office 365 Home Premium everything you do can be shared among the family. Create and share synched calendars in Outlook to keep track of who is where. Use Excel to plan shopping lists that everyone can add to, or a rota for the housework to pin on the fridge.

Use SkyDrive to sync smartphones to your chosen devices, so that your precious snaps – like that photo of Jack blowing out the candles on his first birthday – are automatically sent to every synched device, ready to be shared with other friends and family via email or social media. Or let the children use it to do their homework on the home PC, knowing that they have instant access to it when they reach school the next day.

With Office 365 Home Premium, you'll also be able to explore the full benefits of OneNote, a powerful note taking tool which allows you to save pictures, video, memos and web pages in easy-to-share documents. Create OneNote files that the whole family can become involved in and enjoy. For example, start a summer holiday OneNote in which everyone can have their say about where to go.

Your subscription includes Skype, which will help keep you in touch more easily with friends and family. The Office 365 Home Premium subscription includes 60 minutes of free* international calls every month to landlines in over 40 countries and to mobile phones in seven countries.

Plus Office 365 Home Premium comes with an extra 20GB of SkyDrive* online storage allowing you space to access all the projects you've got going on at any one time.
